Dual Batterty in Patrol 3.0TD

Yes, custom made battery cradles are available, around $90 + supplied only.
The cradles for GQs (and I think GU's) usually mount on passenger side in the centre in front of the overflow bottle or in the passnger side corner depending if your fuel filter is there (depending on model and engine) Oil filter should be on the RHS. At least a TD42 and 2.8 TDi.

You can buy the cradle of the web or ARB, OL etc..

I made my own battery cradle after looking at the ARB type ones for ~$100. The 3.0TD has a real nice clear spot already for the 2nd battery, complete with tapped bolt holes. It is a simple matter to make one up if you have access to a welder. If not, then easy enough to buy as all ARB, TJM, OL etc... stock them.

As for oil filter access, it restricts, but not unreasonably so. You are spoilt for access when no 2nd battery is fitted...lol

Mick,
I've got the ARB cradle fitted, no problem fits on the passengers side, solid as a rock. Oil filter is a bit more of a challenge but you can still get at it easily enough, now I've lifted the suspension 50 mm I got one of the tyre steps as a chrissy present this makes life so much easier, everthing is easier to get at. Keep the shiny side up

I fiited the ARB duel battery kit inc battery cradle.
The cradles are powder coated and easy to fit and will last alot longer than some of those cheap ones.
I think the holders are about $90

Hi Mick
I did the installation myself and it is easy too install.All the cables are at the correct length, all the bolts are in the pack the only thing that is not in the kit is the battery,but you can get one of those as well if you wish.
I think installation was about $100 if i remember correctly
Any other questions let me know here and i will help if i can.

I have the ARB system in mine 03 GU 3.0 - Neat unit no problems.
However do your self a favour and put some insulation around the tray because without a heat sheild the turbo heats up the battery and it boils while charging killing the battery. Just make sure it non flamable - I used foil faced glass wool insulation.
Note the fresh air ducting and shroud on the main battery.
I went for a cheapish wet cell deep cycle batt and now have acid spatters due to a combination of heat, horrid corrigations, and fast charging following deep discharges.
Make sure you check mounting bolts from time to time - trays have worked loose and cracked the wheel arch welds.
